You might want to give the QB accuracy more time. I personally don't ever see low numbers like that. Actually I just played the Browns and their rookie had over 70%. I usually have 50-60 with Mallett. With Romo I was at 60-70.
You might do this already but, it helps when you make all changes outside of your CFM and load them into it.
If your only playing play now games your results might be a little different
